The S.T. Dupont Ligne 1 is a cornerstone of French luxury, representing the brand's transition into high-end gas lighters during the mid-20th century.

What Is S.T. Dupont Ligne 1 Lighter Worth?

The typical price range for S.T. Dupont Ligne 1 Lighter is $200 - $300 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Mechanical functionality and the airtight integrity of the gas seals are primary drivers of market price.
• The physical condition of the gold plating, specifically looking for 'brassing' or wear on the corners and edges.
• Presence of the original presentation box and historical documentation can significantly increase the $200-$300 valuation.
• The clarity and resonance of the signature 'ping' sound when the lid is flipped open.

How to Identify S.T. Dupont Ligne 1 Lighter?

• Verify the 'S.T. Dupont' and 'Paris' hallmarks stamped clearly on the baseplate alongside the 'Made in France' mark.
• Check for the unique serial number hand-struck on the bottom; authentic vintage Ligne 1 numbers are often slightly unevenly aligned.
• Examine the underside of the fuel cap for a specific color-coded paint dot (often red, yellow, or blue) indicating the correct gas refill type.
• Confirm the presence of the signature vertical line engraving which should be crisp and consistent across the gold-plated brass body.
